Product Details

Alina centres a 2.53ct emerald cut lab diamond flanked by two tapered baguettes in 18k white gold. The baguettes are cut to mirror the step-cut character of the emerald cut. Both use the same broad, parallel facets, so the three stones read as a coherent group rather than a centre stone with decorative additions.

The baguettes taper from wide at the centre to narrow at the outer edge, creating a gentle narrowing effect that draws the eye to the emerald cut.
